Title: Electromagnetic coil and manufacture thereof
Inventor: HOUJIYOU FUMIYASU
IPC: H01F5/06
Filed: 1983-10-21
Abstract: PURPOSE:To give an electromagnet coil with good water-proof properties and to facilitate the processes by wrapping and covering the coil with a resin film. CONSTITUTION:Resin films 2a and 2b in the shape of circular sheets whose centers are cut off are brought in contact with both end surfaces of a coil 1 and outer circumference ends and inner circumferential ends are bonded respectively. For the bond, various methods such as thermal pressure contact or bonding with an adhesive 3 can be employed. At bonding, the air in a space between the coil 1 and the films 2a and 2b is exhausted so as to bring the films 2a and 2b in a tight contact with the coil 1. In this case, it is available to interpose an insulating or good-heat-conduction powder or liquid between the coil 1 and the resin films 2a and 2b. Also, an insulating or good-heat-conduction gas can be impregnated after evacuating the air. For this impregnation, it is desirable to provide some inlet.

Title: Camera
Inventor: OKADA NAOSHI
IPC: G03B5/00
Filed: 1991-07-10
Abstract: PURPOSE:To enhance automatic focusing(AF) accuracy at the time of trimming and to obtain a photograph having high image quality even at the time of trimming photographing in a camera capable of trimming. CONSTITUTION:Information on optical zooming in the case of AF is stored in a memory in a photographing lens. Information on trimming (electronic zooming) is similarly stored in the memory, and the defocusing amount of the photographing lens is corrected in the case of performing electronic zooming. For example, focusing detecting areas FA, FA1, and FA2 are all effective when electronic zooming(EZ) is 1.4-power, but it is only the FA that is effective when EZ is 1.7-power. AF action is performed based on such information as is written in the memory.

Title: Tire for motorcycle
Inventor: NAKAMURA KAZUMI
IPC: B60C11/11
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the skidding performance during cornering in a tire for use in motorcycles without impairing the traction performance on a muddy ground. SOLUTION: In order to obtain the traction performance, many cross direction block-rows 14 are provided in the circumferential direction of the tire. Third blocks 16 the block height of which is lower than that of the cross direction block-rows 14 and which are long in the circumferential direction of the tire, are provided between the cross direction block-rows 14. Since the third blocks 16 resist the flow of mud across the tire-width between the cross direction block-rows 14, the skidding performance is improved to improve the cornering performance of the tire on the muddy ground. Further, since the height of the third blocks 16 is set to be lower than that of the cross direction block-rows, the flow of mud between the cross direction block-rows 14 is not completely blocked up.  Thus, the mud-flowability is ensured to prevent the mud from being clogged between the cross direction block-rows 14.

Filed: 1986-08-25
Abstract: PURPOSE:To reduce the size, weight, and cost of an optical isolator, by providing an optical waveguide and a grating coupler and 1/4-wave plate installed to the optical waveguide. CONSTITUTION:A luminous flux 20 is guided into an optical waveguide 9 and propagated as TE-mode parallel wave-guided light 10. The light 10 is diffracted by a grating coupler 11 and made incident on a substrate 21 in the direction from the top to the bottom as linearly polarized light 12 having the plane of vibration in the C-C direction. The linearly polarizing light 12 is made incident on an 1/4-wave plate 15 after advancing straight through an optical waveguide 13 without being diffracted by a grating coupler 14 and emitted as circularly polarized light 16. On the other hand, when the same circularly polarized light 17 as the emitted light 16 is made incident on the wave plate 15 from the bottom, the light after passing through the wave plate 15 becomes linearly polarized light having the plane of vibration in the B-B direction and made incident on the optical waveguide 13. The linearly polarized light made incident on the waveguide 13 is diffracted by the grating coupler 14 and emitted as a luminous flux 22 after it is propagated in the C-C direction as TE-mode wave-guided light 19. The other part of the incident light 17 is not diffracted, but emitted to the outside as linearly polarized light 23.

Title: Process of cleaning semiconductor wafer and device thereof
Inventor: OMORI MASASHI
IPC: H01L21/304
Filed: 1989-07-28
Abstract: PURPOSE:To remove any foreign matters without fail by a method wherein a cleaning solution is fed to a pressure-reduced processing vessel so as to immerse an wafer therein; an inert gas is fed to the vessel upto a specific air pressure; pure water containing the least soluble O2 is substituted for the cleaning solution in the vessel in sealed state to be drained; and the vessel is pressure-reduced to dry up the wafer. CONSTITUTION:A processing vessel 51 is pressure-reduced by a pressure-reducing pipe 57 and then cleaning solution is fed from a pipe 55 to immerse a wafer 62 in the cleaning solution. Next, N2 is fed from another pipe 54 to be pressurized upto a specific pressure. Accordingly, the cleaning solution sufficiently extends to every corner of wafer recess. Successively, pure water containing little dissolved oxygen is fed from the other pipe 56 to the vessel 51 in the sealed state so as to be substituted for the cleaning solution. By this processing, the reaction of Si in wafer to O is restrained to avoid the production of colloidal silica. Next, the pure water is drained and the vessel 51 is pressure-reduced again to dry up the wafer 62. In such a constitution, any foreign matters can be removed from the wafer 62 without fail while avoiding the production of the secondary pollutants such colloidal silica, carbon compound, etc.

Title: Projecting device for exposing slit
Inventor: TOKUHARA MICHIHIRO
IPC: G02B13/00
Filed: 1984-09-20
Abstract: PURPOSE:To reduce the titled device at its size by cutting off a part of an image formation optical system so that the size of a pupil in the longitudinal direction of a slit is reduced. CONSTITUTION:The peripheral part of a lens is cut off in the longitudinal direction of the slit so that the size of an exit pupil 1b is reduced smaller than that of an exit pupil 1a. The latitudinal direction of the slit is the scanning direction of a copying machine and the height H' of a final lens surface 2 from the optical axis is considerably smaller than the necessary height H of the lens. Light flux from the pupil is not reflected in the longitudinal direction of the slit. The thickness of a body tube 3 in the latitudinal direction of the slit can be made comparatively thin by cutting the circular exit pupil from its upper and lower parts in parallel with the longitudinal direction of the slit. Consequently, the optical system can be reduced at its size. In the copying device, the height direction can be reduced at its size and the effective width of a mirror can be contracted.

Title: Control system for fuel cell power generation plant
Inventor: MATSUMURO HARUO
IPC: H01M8/04
Filed: 1984-09-21
Abstract: PURPOSE:To assure given amounts of steam so as to achieve improved control of a cell cooling water system by making control of the temperature of water for cooling a fuel cell and control of the temperature of a steam generator independent and temporarily reducing the internal pressure of the steam generator during a rapid increase of the load. CONSTITUTION:On the basis of an actual current signal from a current detector 29, a function generator 30 delivers a signal indicating the temperature of cooling water for maintaining the temperature of a fuel cell by taking the heat generated by the reaction of the fuel cell 5 into account. The above temperature-indicating signal and an actual temperature signal generated by a temperature detector 21 are subjected to deviation operation in a comparator 31 and the result of the operation is transferred to a valved 17 for controlling the temperature of water for cooling the fuel cell through an output control computing element 32. As the result, part of the steam from a steam generator 15 is cooled by a heat exchanger 20 to produce water. The temperature of water for cooling the fuel cell is controlled by varying the amount of thus produced water n the steam. By thus independently controlling the temperature of water for cooling the fuel cell 5 and that of the steam generator 15, it is possible to stably supply steam to a mixer 14. Furthermore, it is also possible to prevent any decrease in the pressure and the temperature of the steam generator 15 during application of a high load.
